I spent two nights in this former apartment building which has been converted into a Kimpton boutique hotel, two blocks from Dupont Circle. My room, facing the back of the building on a high floor, had no noise, and a great view of the National Cathedral and more. It was quite large -- it appears to have been a studio apartment in a previous life, but it's now outfitted in classic Kimpton style, with an amazingly comfortable bed and all the amenities you'd expect from Kimpton (animal print robes, bright orange umbrella, minibar, etc)
The sink was outside the bathroom door; the bathroom itself had just enough room for the toilet and tub. The tub/shower is not very wide; neither am I, but if you are, you might find the bathroom a bit cramped.
I appreciated the eco-friendly practices, including the soap and shampoo dispensers in the shower rather than mini plastic bottles, but it took a lot of pumping to get anything to come out of the dispensers.
The staff in the small lobby/entranceway were very accommodating and service-oriented (printing boarding passes, calling taxis, extending my check out time, etc.), although some seemed a little less experienced and polished than at other Kimpton hotels where I've stayed. Waitstaff in the restaurant was very accommodating and helpful; food was excellent; all maintenance and housekeeping staff who I met in the hallways or elevators were beyond friendly.
The two small elevators were a bit slow and one of them had a door that was quite unforgiving for those in the lobby awaiting a ride upstairs -- on more than one occasion, by the time everyone coming down got out, the door was closing and would not reopen to take guests upstairs, no matter how hard we pushed the button or tried to hold the door physically, but a staff member came running and wedged himself into the closing door and pushed the "open door" button from the inside and saved the day; once I learned that trick, I practiced it for others.
I found the Kimpton secret password on Facebook and used it on check-in and was given my choice of a free continental breakfast (which I opted for and which says "no substitutions" on it and on the menu, but the waitstaff offered me $7.50 discount off my bill if I used the coupon for breakfast off the menu) , free parking, a free cocktail, or an additional raid the minibar coupon.
This is the third Kimpton Hotel I've stayed at in Washington (including the Helix and the Hotel Rouge). I would gladly stay at any of the three again, though The Madera is more for grown ups than the Helix.
